网络控制传输时延的补偿控制方法研究

Compensation Control Method of Network Control Transmission Time Delay

针对网络控制系统具有不确定时延的特性,利用广义预测控制算法对不确定时延的超强适应性,同时结合缓冲区、事件时间混合驱动以及时间标志信息提出一种解决网络随机传输时延、时序错乱和数据包丢失的综合补偿控制方案,从而有效地克服系统在实际运行过程中存在的不确定性问题,取得了很好的控制效果.仿真结果验证了该方案的有效性.

With regard to uncertain delay of the network control system, through using generalized predictive control （GPC） algorithm for the adaptability of uncertain delay, combining with the buffer and event - time driven and time -stamp, a comprehensive compensation control solution is provided in this paper, which solves random network transmission latency, time -sequence confusion and data packet loss, so effectively overcome uncertainty of actual system operation, with an ideal control effect. The effectiveness of the solution is shown through simulation results.
